Doc excerpts, as a teaser: - SDF JKL layout keeps me on home row, ready to type Forth. - 39 columns source text to fit the C64 screen. - `0 prof` patches the first instruction to an `rts`, disabling the profiler. `1 prof` restor

> - Function composition was being used as a binary operator between two functions. You just replaced the infix notation with prefix notation. That's incorrect. Here's the definition of function compose: (f . g) x = f (g x)

From the article: length = foldr (+) 0 . map (const 1) length2d = foldr (+) 0 . map length -- and the proposed syntax the author calls more readable: length = foldr((+), 0, $) . map(const(1), $) length2d = foldr((+),

Yeah, this. Plus a mistake from the article: $ echo '*\n!.gitignore' > build/.gitignore The \n won't be interpreted specially by echo unless it gets the -e option. Personally if I need a build directory I just

"Agreement" of time is probably nonsense, yeah. I realized after posting so I edited in the parenthetical, but as [3] notes, locality probably makes this less of a real issue. Apparently with the birthday paradox 32 bit random IDs

I forget the context but the other day I also learned about Snowflake IDs [1] that are apparently used by Twitter, Discord, Instagram, and Mastodon. Timestamp + random seems like it could be a good tradeoff to reduce the ID sizes and still

I think everyone agrees with the sentiment but practically speaking that ship sailed decades ago. Browsing the web without uBlock or similar is ill-advised. Morbidly curious, I turned off my blockers and it's not as bad as I expected h

Oh, it's a list you can add to your uBO. I thought it was a descriptive headline: "(The) uBlock filter list (is going) to hide ..." I only watch Youtube via browser now for both adblocking and my own custom userscripts, both

It seems to me that AI is mostly optimized for tricking suits into thinking they don't need people to do actual work. If I hear "you're absolutely right!" one more time my eyes might roll all the way back into my head. S

I actually have the below clashes function in my bashrc to detect overloaded names, and a few compgen aliases for sorted formatted command lists. Clashes takes a few seconds to chew through the 3000ish commands on my Steam Deck. I also di

(Edit: in the old post title:) "everything is a value" is not very informative. That's true of most languages nowadays. Maybe "exclusively call-by-value" or "without reference types." I've only read t

Strange. Middle-clicking the link opens a HackerNews frontpage, but copypasting into a new tab shows the article. Presumably the server shoos away referer links? To reduce load maybe somehow? Or maybe something's weird in my own config

Haskell, then. f x = let y = x + 1 in y + 1 Same deal. In (f 3), y = 4, in (f 7), y = 8. y varies but cannot mutate. Should be a true enough Scottsman.

by ekipan 8mo ago
Mutability is distinct from variability. In Javascript only because it's a pretty widely known syntax: const f = (x) => { const y = x + 1; return y + 1; } y is an immutable variable. In f(3), y is 4, and in

That makes me sad. I also love Posy's content, I'm using his cursors right now, and this new knowledge that there is some of it I cannot see gives me real consumerist FOMO anxiety. A little digging and I couldn't find anythin

Cool enough I suppose, but the framing had me expecting the more farty twisted squarenoise instruments like in Wario Lands 1-3, and less smooth sines and squares. I tried out Kimi No Shiranai Monogatari and Daft Punk's Aerodynamic. ht

A fine sentiment, and would probably even be somewhat enforceable, as most AI slop is pretty obvious, but I suspect a lot isn't. You'd have to decide where to draw the line. How much LLM assistance transitions a work from HackerNe

I'm sad that Platine Dispositif pulled their games. Chelsea Has to Beat the Seven Devils to Death (known more widely in English as Bunny Must Die) was a lot of fun and one day I'd like to play some of their others, but they mostly

This is a tangent on language semantics (of the English kind) instead of engaging with the (interesting!) narrative on miscompiles. Feel free to skip. > A compiler is a translator that translates between two different languages. I lament

I confess I'm still pretty new to git. I haven't had a very long time to wed myself to git's index and its presence makes me do extra ceremony that I resent whenever I want to polish my graph for my personal projects. The mai

I've not tried jj yet so I can only speak to impressions, and those impressions appeal to me a lot. My understanding is that jj amends all the changes in _now_ so there's only one place where changes live: the commit graph. No ind

Hard agree. Literally every Windows editor I've ever used, except Notepad, allows me to configure it to save CRLF or LF or sometimes even CR files. And I always just leave it on LF because it's easier. Old Notepad support should n

You could try posting both at the LLM and ask it to explain the stuff I changed, if you're interested in learning more Javascript. Assuming you aren't already deep in the JS trenches and only vibed bc you couldn't be bothered

Cannot stand robot code. Thanks for the genuinely cool thing though. I hope you don't mind me rewriting, if only for my own satisfaction. { const s = window.scroller = {} const press = (key, code) => () => docum
